Three point bending data for the fibers oriented rotationally in one direction 90 degrees from the other (in Fig2C).

Here the file convention reads  number_90_digit1_digit2.csv. 

number = one, two or three ---- indexes specimen. 
digit1 = 1 or 2 ---- 1 = unjammed, 2 = jammed. 
digit 2 = 1 --- just a file convention suffix.

The average is taken with mean() and the standard deviation with std() matlab functions for the three samples in jammed and unjammed cases.
